Description

本発明は、給袋マガジン内に略水平状態で積載収容した空袋を、袋詰め包装機やスパウト付き袋製造装置(スパウト取付機)などの処理装置に、順次供給するための空袋供給方法及び空袋供給装置に関する。   The present invention provides an empty bag supply method for sequentially supplying empty bags loaded and accommodated in a bag supply magazine in a substantially horizontal state to a processing apparatus such as a bag filling and packaging machine or a spout-equipped bag manufacturing apparatus (spout attachment machine). And an empty bag supply device.

特許文献1〜4に示すように、給袋マガジンに積載収容(コンベアマガジン式給袋装置のように上部の袋が前方側にくるように縦方向にずらして積載した状態を含む)した空袋のうち最上位の空袋から順次1枚ずつ取り出し、袋詰め包装機やスパウト付き袋製造装置に対し供給することは周知である。
この場合に、給袋マガジン内に積載収容された空袋群が、静電気等により密着状態にある場合、最上位の空袋を吸盤で吸着保持して上方に取り出した際、その下の空袋(1枚又は複数枚)も一緒に取り出され、そのまま袋詰め包装機やスパウト付き袋製造装置に供給されるという不具合(以下、単に複数枚取り供給という)が生じる場合がある。
As shown in Patent Documents 1 to 4, empty bags loaded and stored in a bag supply magazine (including a state in which the upper bag is shifted and stacked vertically so that the upper bag comes to the front side like a conveyor magazine type bag supply device) It is well known that one sheet is taken out from the uppermost empty bag one by one and supplied to a bagging and packaging machine or a spouted bag manufacturing apparatus.
In this case, when the empty bag group loaded and accommodated in the bag supply magazine is in a close contact state due to static electricity or the like, when the uppermost empty bag is sucked and held with a suction cup, the empty bag underneath is removed. There may be a problem (hereinafter simply referred to as “multiple-sheet feeding”) in which (one or a plurality of sheets) are also taken out and supplied to a bagging and packaging machine or a spouted bag manufacturing apparatus as it is.

この複数枚取り供給を防止するため、特許文献1では、給袋マガジンの両側壁の上方に、吸盤で持ち上げられる空袋に接触する抵抗体を設置して、一緒に持ち上げられた2枚目以降の空袋が最上位の空袋から引き離されるようにし、特許文献2では、位置決めバーで空袋の中央部を軽く押さえた状態で最上位の空袋の先端側を吸着し、吸盤を少し回動して空袋の先端側を少しめくって最上位の空袋と2枚目の空袋の間に空気を流入させた後、吸盤を上方に持ち上げるようにしている。   In order to prevent this supply of multiple sheets, in Patent Document 1, a resistor that contacts an empty bag lifted by a suction cup is installed above both side walls of the bag supply magazine, and the second and subsequent sheets lifted together. In Japanese Patent Application Laid-Open No. 2004-228688, the top end of the top empty bag is adsorbed while the center of the empty bag is lightly held by the positioning bar, and the suction cup is turned slightly. After moving, the tip side of the empty bag is slightly turned to allow air to flow between the uppermost empty bag and the second empty bag, and then the suction cup is lifted upward.

実用新案登録第2588135号公報Utility Model Registration No. 2588135 特許第3084539号公報Japanese Patent No. 3084539 特開2006−36325号公報JP 2006-36325 A 特開2006−224546号公報JP 2006-224546 A

上記の対策はいずれも、給袋マガジン内の最上位の空袋を吸盤で吸着して上方に取り出す際に、その下の袋を分離しようとしたものであるが、装置の高速化が望まれる昨今、空袋を取り出す時間も短縮される結果、分離効果を得ることが余り期待できなくなっている。
一方、給袋マガジン内から空袋を取り出す吸盤から前記空袋を受け取り所定位置に移送する移送手段として同じく吸盤を用いる場合(特許文献3参照)、吸盤による移送中に、吸着した空袋(最上位の空袋)とそれに密着していた空袋(2枚目以降の空袋)の間に空気が流入し、両者が分離して2枚目以降の空袋の落下を期待することができるが、当該空袋がどこで落下するか分からず、その落下箇所によっては次の空袋の取り出しに支障が出る場合も考えられる。
All of the above measures try to separate the lower bag when the uppermost empty bag in the bag supply magazine is picked up by the suction cup and taken out upward, but speeding up of the device is desired. Recently, as a result of shortening the time for taking out the empty bag, it is not much expected to obtain a separation effect.
On the other hand, when the suction cup is also used as the transfer means for receiving the empty bag from the suction cup for taking out the empty bag from the bag supply magazine and transferring it to a predetermined position (see Patent Document 3), Air flows between the upper empty bag) and the empty bag (the second and subsequent empty bags) that are in close contact with them, and the two can be separated and the second and subsequent empty bags can be expected to fall. However, it is not possible to know where the empty bag falls, and depending on the location of the drop, there may be a problem in taking out the next empty bag.

本発明は、このような従来技術の問題点に鑑みてなされたもので、給袋マガジン内に略水平姿勢で積載収容された空袋群から最上位の空袋を取り出して袋詰め包装機やスパウト付き袋製造装置に供給する場合に、複数枚取り供給を防止することを主たる目的とする。また、複数枚取りが生じた場合に、2枚目以降の空袋の落下が次の給袋の妨げにならないようにすることを他の目的とする。   The present invention has been made in view of such problems of the prior art, and takes out the uppermost empty bag from an empty bag group loaded and accommodated in a substantially horizontal posture in a bag supply magazine, When supplying to a spouted bag manufacturing apparatus, the main purpose is to prevent supply of multiple sheets. Another object is to prevent the fall of the second and subsequent empty bags from interfering with the next bag supply when multiple sheets are taken.

本発明に係る空袋供給方法は、給袋マガジン内の最上位の空袋の供給方向前端付近の上面を第1吸着部材で吸着した後、前記第1吸着部材を上方へ移動させて前記空袋を持ち上げ、持ち上げた前記空袋の前端付近を挟持部材で挟持し、前記挟持部材を移動させて前記空袋を所定位置まで移送するとともに略垂直姿勢に変更し、略垂直姿勢の前記空袋の供給方向前面のみを第2吸着部材で吸着した後、前記第2吸着部材を移動させて前記空袋を所定位置まで移送し、隣接する処理装置へ引渡すことを特徴とする。 In the empty bag supply method according to the present invention, after the upper surface of the uppermost empty bag in the bag supply magazine near the front end in the supply direction is adsorbed by the first adsorbing member, the first adsorbing member is moved upward to move the empty bag. Lifting the bag, holding the vicinity of the front end of the lifted empty bag with a holding member, moving the holding member to transfer the empty bag to a predetermined position, and changing to a substantially vertical posture, the empty bag in a substantially vertical posture After adsorbing only the front surface in the supply direction with the second adsorbing member, the second adsorbing member is moved to transfer the empty bag to a predetermined position and delivered to an adjacent processing apparatus.

この空袋供給方法は、前記第2吸着部材を移動させて前記空袋を所定位置まで移送する際に、前記空袋を略垂直姿勢から略水平姿勢に変更する場合を含む。この場合、前記第2吸着部材が1枚の空袋に付き複数個あり、前記第2吸着部材で前記空袋の供給方向前面の少なくとも上下2カ所を吸着して、移送中に前記空袋の姿勢を安定させておくことが望ましい。典型的な例では、前記空袋は前記給袋マガジン内で袋口側又は袋底側を供給方向に向けて置かれ、前記空袋を略水平姿勢に変更する際、略鉛直姿勢だった前記空袋の下方側を供給方向前方側に向かせ、これにより前記空袋の袋口側と袋底側の向きを前記給袋マガジン内とは逆転させる。   The empty bag supply method includes a case where the empty bag is changed from a substantially vertical posture to a substantially horizontal posture when the second adsorbing member is moved to transfer the empty bag to a predetermined position. In this case, there are a plurality of the second adsorbing members attached to one empty bag, and the second adsorbing member adsorbs at least two upper and lower portions on the front surface in the supply direction of the empty bag, It is desirable to keep the posture stable. In a typical example, the empty bag is placed in the bag supply magazine with the bag mouth side or the bag bottom side facing the supply direction, and when the empty bag is changed to a substantially horizontal posture, the empty bag is in a substantially vertical posture. The lower side of the empty bag is directed to the front side in the supply direction, whereby the direction of the bag mouth side and the bag bottom side of the empty bag is reversed from that in the bag supply magazine.

本発明に係る空袋供給装置は、下方の第1受取り位置とその上方に設定した第1引渡し位置の間で往復移動し、第1受取り位置において給袋マガジン内の最上位の空袋の供給方向前端付近の上面を吸着し、第1引渡し位置にきて吸着した前記空袋を持ち上げる第1吸着部材と、前記第1吸着部材に前記両位置の間で往復移動を行わせる第1吸着部材移動機構と、第2受取り位置と第2引渡し位置の間で往復移動し、第2受取り位置から第2引渡し位置に移動する間に挟持面が略水平状態から略垂直状態に変更され、第2受取り位置において前記第1引渡し位置にきた第1吸着部材に吸着された前記空袋の前端付近を挟持し、第2引渡し位置にきたとき挟持した前記空袋を略垂直姿勢で吊り下げる挟持部材と、前記挟持部材に前記両位置の間で往復移動を行わせる挟持部材移動機構と、第3受取り位置と第3引渡し位置の間で往復移動し、第3受取り位置において前記第2引渡し位置にきた前記挟持部材に挟持された前記空袋の供給方向前面のみを吸着し、第3引渡し位置にきて前記空袋を隣接する処理装置へ引き渡す第2吸着部材と、前記第2吸着部材に前記両位置の間で往復移動を行わせる第2吸着部材移動機構を備える。 The empty bag supply device according to the present invention reciprocates between a first receiving position below and a first delivery position set above the first receiving position, and supplies the uppermost empty bag in the bag supply magazine at the first receiving position. A first adsorbing member that adsorbs the upper surface near the front end in the direction and lifts the adsorbed empty bag at the first delivery position, and a first adsorbing member that causes the first adsorbing member to reciprocate between the two positions The reciprocating movement between the moving mechanism and the second receiving position and the second delivery position is performed, and the holding surface is changed from the substantially horizontal state to the substantially vertical state while moving from the second receiving position to the second delivery position. A holding member that holds the vicinity of the front end of the empty bag adsorbed by the first adsorbing member at the first delivery position at the receiving position and suspends the empty bag held at the second delivery position in a substantially vertical posture; Between the two positions on the clamping member A holding member moving mechanism that performs a backward movement, and a reciprocating movement between the third receiving position and the third delivery position, and the empty bag held by the holding member that has come to the second delivery position at the third receiving position. A second adsorbing member that adsorbs only the front surface in the supply direction, moves to the third delivery position and delivers the empty bag to the adjacent processing device, and causes the second adsorbing member to reciprocate between the two positions. An adsorption member moving mechanism is provided.

この空袋供給装置は、前記第2吸着部材が第3受取り位置から第3引渡し位置に移動する間に、前記第2吸着部材の吸着面を略垂直状態から略水平状態に変更することを含む。この場合、前記空袋は略垂直姿勢から略水平姿勢に変更される。
この場合、前記第2吸着部材が1枚の空袋に付き複数個あり、それらが上下に配置されて前記空袋の供給方向前面の少なくとも上下2カ所を吸着するようになっていることが望ましい。典型的な例では、前記第2吸着部材が第3受取り位置から第3引渡し位置に移動する間に、前記第2吸着部材の吸着面が略垂直状態から下向きの略水平状態に変更される。これにより前記空袋の袋口側と袋底側の向きは前記給袋マガジン内とは逆転する。
The empty bag supply device includes changing the suction surface of the second suction member from a substantially vertical state to a substantially horizontal state while the second suction member moves from the third receiving position to the third delivery position. . In this case, the empty bag is changed from a substantially vertical posture to a substantially horizontal posture.
In this case, it is desirable that there are a plurality of the second adsorbing members attached to one empty bag, and they are arranged one above the other so as to adsorb at least two places on the front surface in the supply direction of the empty bag. . In a typical example, while the second suction member moves from the third receiving position to the third delivery position, the suction surface of the second suction member is changed from a substantially vertical state to a downward substantially horizontal state. Thereby, the direction of the bag mouth side and the bag bottom side of the empty bag is reversed from that in the bag supply magazine.

上記空袋供給装置は、さらに、前記挟持部材の第2引渡し位置の下方位置に設置され、前記挟持部材及び前記挟持部材が挟持した空袋との干渉を避ける退避位置と第3受取り位置にきた前記第2吸着部材の吸着面に対向する吸着補助位置の間を往復移動する吸着補助部材を含み得る。この場合、前記吸着補助部材は、前記吸着補助位置において、第3受取り位置にきた前記第2吸着部材の吸着面に対向して、第2引渡し位置にきた前記挟持部材に挟持された前記空袋の供給方向後面側を支持するように配置される。   The empty bag supply device is further installed at a position below the second delivery position of the holding member, and has come to a retracted position and a third receiving position to avoid interference between the holding member and the empty bag held by the holding member. A suction assisting member that reciprocates between suction assisting positions facing the suction surface of the second suction member may be included. In this case, the suction assisting member is opposed to the suction surface of the second suction member at the third receiving position at the suction assisting position, and is held by the clamping member at the second delivery position. It arrange | positions so that the supply surface rear side may be supported.

さらに、上記空袋供給装置において、前記挟持部材の挟持片の一方(挟持部材が第2引渡し位置にきたとき、空袋の供給方向後方側に位置する挟持片)に、第3受取り位置にきた前記第2吸着部材の吸着面に対向する延長部を形成し、前記挟持部材が第2引渡し位置にきたとき前記延長部に前記空袋の供給方向後面側を支持させることができる。   Furthermore, in the above-described empty bag supply device, one of the holding pieces of the holding member (the holding piece located on the rear side in the supply direction of the empty bag when the holding member comes to the second delivery position) is at the third receiving position. An extension portion facing the suction surface of the second suction member can be formed, and when the clamping member comes to the second delivery position, the extension portion can support the rear side in the supply direction of the empty bag.

本発明によれば、給袋マガジンから第1吸着部材で最上位の空袋を取り出すとき、複数枚取りが生じたとしても、その空袋を挟持部材で挟持し、略水平姿勢から略垂直姿勢に変換しながら移送する過程で、空袋間に空気が流入して密着状態が解消し、次に第2吸着部材で空袋の袋面(空袋の供給方向前面のみ)を吸着し挟持部材の挟持から空袋を開放すると、実際に第2吸着部材により吸着された空袋以外の空袋(複数枚取りされた余分の空袋)は落下する。従って、複数枚取り供給が防止できる。
また、給袋マガジンから第1吸着部材で吸着して持ち上げた空袋を、挟持部材で挟持して移送するので、その移送中に空袋が落下することはなく、第2吸着部材で空袋の袋面を吸着し挟持部材の挟持から空袋を開放してすぐに落下するので、給袋マガジンからの空袋の取り出しに支障が出ることはなく、安定した給袋が可能であり、しかも落下する空袋はほぼ決まった位置に落下する。
According to the present invention, when the uppermost empty bag is taken out from the bag supply magazine by the first suction member, even if a plurality of sheets are picked up, the empty bag is held by the holding member, and the substantially horizontal posture is changed to the substantially vertical posture. In the process of transferring while converting into air, air flows between the empty bags and the contact state is resolved, and then the second adsorbing member adsorbs the empty bag surface (only in front of the empty bag supply direction) and holds the holding member. When the empty bag is released from the nipping, empty bags other than the empty bag actually adsorbed by the second adsorbing member (excess empty bags taken by a plurality of sheets) fall. Therefore, it is possible to prevent a plurality of sheets from being supplied.
Further, since the empty bag attracted and lifted from the bag supply magazine by the first adsorbing member is nipped and transferred by the holding member, the empty bag does not fall during the transfer, and the second adsorbing member does not drop the empty bag. The bag surface is adsorbed and the empty bag is released from the pinching of the holding member and immediately falls, so there is no hindrance to taking out the empty bag from the bag supply magazine, and stable bag supply is possible. The falling empty bag falls to a fixed position.

以下、図1〜図4を参照して、本発明をより具体的に説明する。

第1吸着部材26は、前記第1受取り位置において、吸着面が略水平下向きとなり、ストッパー9に当接して位置決めされたコンベアマガジン7a内の空袋4の供給方向前端付近の上面を吸着する。続いて後方側(空袋4の供給方向の後方側)に揺動しながら上昇して前記第1引渡し位置に移動し、吸着した空袋4を持ち上げて前端部分を引き起こす。第1吸着部材26は1枚の空袋に付き2個(左右一対)が設置されている(図5の吸着部位A参照)。
The empty bag supply device 8 receives a bag 4 from the conveyor magazine 7a, receives the bag 4 from the empty bag take-out means, transfers the bag 4 along an arcuate path, and changes it to a substantially vertical posture. It consists of a bag transfer means and a second empty bag transfer means that receives and transfers the bag 4 from the first empty bag transfer means and places it on the bag support portion 3 of the spouted bag manufacturing apparatus 1 after changing to a horizontal posture.
The empty bag taking-out means is reciprocated between the first adsorbing member 26 that reciprocates between a first receiving position below and a first delivery position that is set above the first adsorbing member 26, and between the two positions. A first adsorbing member moving mechanism 27 is provided. In FIG. 2, the first suction member 26 is drawn with a solid line at the first receiving position, with a virtual line at the first delivery position, and its movement path is drawn with a double arrow. As a part of the first suction member moving mechanism 27, a lever 28 that supports the first suction member 26 and a shaft 29 to which the lever 28 is fixed are shown. Needless to say, the first adsorbing member 26 communicates with a switching valve and a vacuum source (not shown) through vacuum piping.
The first suction member 26 sucks the upper surface near the front end in the supply direction of the empty bag 4 in the conveyor magazine 7a positioned in contact with the stopper 9 with the suction surface facing substantially horizontally downward at the first receiving position. Subsequently, it moves upward while swinging backward (backward in the supply direction of the empty bag 4) and moves to the first delivery position, lifting the adsorbed empty bag 4 and causing the front end portion. Two first adsorbing members 26 (a pair of left and right) are installed per one empty bag (see adsorbing part A in FIG. 5).

前記第1空袋移送手段は、下方の第2受取り位置と、そこから上方前方側(空袋4の供給方向の前方側)に円弧状に上昇した第2引渡し位置の間で往復移動する挟持部材31と、挟持部材31に前記両位置の間で往復移動を行わせる挟持部材移動機構32を備える。なお、図2において、挟持部材31は、第2受取り位置では仮想線で、第2引渡し位置では実線で描かれ、その略円弧状の移動経路が両矢印で描かれている。
挟持部材31は、図3に示すように2枚の袋4を同時に挟持できる幅(水平方向幅)を有する2つの挟持片33,34を有し、このうち第2引渡し位置にきたとき後方側(空袋4の供給方向の後方側)に位置する挟持片34は、図5に示すように、袋4の幅方向中央部に相当する位置に舌片状に延びた延長部34aを有する。挟持片34は後述する揺動レバー35に固定され、挟持片33は揺動レバー35に袋4の供給方向に沿った鉛直面内において揺動自在に軸支され、同じく揺動レバー35に取り付けられたエアシリンダ36の作動によって開閉する。
The first empty bag transfer means is sandwiched to reciprocate between a lower second receiving position and a second delivery position that rises in an arc from the lower second receiving position to the upper front side (the front side in the supply direction of the empty bag 4). A member 31 and a sandwiching member moving mechanism 32 that causes the sandwiching member 31 to reciprocate between the two positions are provided. In FIG. 2, the clamping member 31 is drawn with an imaginary line at the second receiving position and with a solid line at the second delivery position, and a substantially arcuate movement path is drawn with a double-headed arrow.
As shown in FIG. 3, the holding member 31 has two holding pieces 33 and 34 having a width (horizontal width) that can hold the two bags 4 at the same time. As shown in FIG. 5, the holding piece 34 located on the rear side in the supply direction of the empty bag 4 has an extension 34 a that extends in a tongue-like shape at a position corresponding to the widthwise center of the bag 4. The sandwiching piece 34 is fixed to a swing lever 35 described later, and the sandwiching piece 33 is pivotally supported by the swing lever 35 in a vertical plane along the supply direction of the bag 4, and is similarly attached to the swing lever 35. The air cylinder 36 is opened and closed by the operation.

前記挟持部材移動機構は、前記揺動レバー35と、ボックスフレーム30に回転自在に軸支された支点軸37と、支点軸37に一端が固定され、他端が揺動レバー35の中間位置に固定された軸部40に回転自在に連結された揺動アーム38と、揺動レバー35の後端とボックスフレーム30に設置されたリンク支持部材39の間を連結するリンク41と、一端が支点軸37に固定され、他端が連結部材42を介して図示しない駆動源に連結され上下揺動する昇降レバー43からなる(図4参照)。昇降レバー43が上下揺動することにより、揺動アーム38が袋4の供給方向に沿った垂直面内において揺動し、さらに揺動レバー35が略円弧状の経路で揺動し、挟持部材31が前記第2受取り位置と第2引渡し位置の間を前記移動経路に沿って往復移動する。   The holding member moving mechanism includes the swing lever 35, a fulcrum shaft 37 rotatably supported on the box frame 30, one end fixed to the fulcrum shaft 37, and the other end at an intermediate position of the swing lever 35. A swing arm 38 rotatably connected to the fixed shaft portion 40, a link 41 connecting the rear end of the swing lever 35 and the link support member 39 installed on the box frame 30, and one end as a fulcrum The elevator 37 is fixed to the shaft 37, and the other end is connected to a drive source (not shown) via a connecting member 42 and swings up and down (see FIG. 4). As the elevating lever 43 swings up and down, the swinging arm 38 swings in a vertical plane along the supply direction of the bag 4, and the swinging lever 35 swings along a substantially arcuate path, and the clamping member 31 reciprocates between the second receiving position and the second delivery position along the movement path.

挟持部材31は、昇降レバー43の揺動に伴い、挟持片33,34が開いた状態で下降し、前記第2受取り位置にきて閉じ、これにより前記第1引渡し位置にきた第1吸着部材26により引き起こされた袋4の前端部を全幅にわたって挟持し、続いて第1吸着部材26が大気開放されて袋4が第1吸着部材26から解放された後上昇し、前記第2引渡し位置に向けて上昇移動する間に挟持面が略水平状態から略垂直状態に変更され、前記第2引渡し位置にきたとき挟持した空袋4を略垂直姿勢で吊り下げる。
なお、図5に示すように、第1吸着部材26の吸着部位Aは挟持片34の延長部34aの両側に設定されている。従って、第2受取り位置にきた挟持部材31と第1吸着部材26は互いに干渉しない。
As the lifting lever 43 swings, the clamping member 31 descends with the clamping pieces 33 and 34 opened, and closes at the second receiving position, whereby the first suction member comes to the first delivery position. The front end portion of the bag 4 caused by the belt 26 is clamped over the entire width, and then the first suction member 26 is released to the atmosphere and the bag 4 is lifted after being released from the first suction member 26, and then moved to the second delivery position. During the upward movement, the holding surface is changed from the substantially horizontal state to the substantially vertical state, and the empty bag 4 held when the second delivery position is reached is suspended in a substantially vertical posture.
As shown in FIG. 5, the suction site A of the first suction member 26 is set on both sides of the extension 34 a of the sandwiching piece 34. Therefore, the clamping member 31 and the first suction member 26 that have come to the second receiving position do not interfere with each other.

前記第2空袋移送手段は、上方の第3受取り位置と、そこから下方前方側(空袋4の供給方向の前方側)に下降した第3引渡し位置の間で往復移動する2個の第2吸着部材44,45と、第2吸着部材44,45に前記両位置の間で往復移動を行わせる第2吸着部材移動機構46を備える。なお、図2において、第2吸着部材44,45は、第3受取り位置では実線で、第3引渡し位置では仮想線で描かれている。この袋供給装置8はW型であるので、第2吸着部材44,45は各袋4に対して1組、合計2組設置されている。
第2吸着部材44,45(前記第3受取り位置において上側に位置するのが第2吸着部材44、下側に位置するのが第2吸着部材45)は所定長さの導管47で連結され、第2吸着部材44の導管48が後述する取付ステー49に固定され、さらに真空配管51により図示しない切換弁及び真空源に連通している。
The second empty bag transfer means has two second reciprocating movements between an upper third receiving position and a third delivery position descending downward from the third receiving position (front side in the supply direction of the empty bag 4). 2 adsorption members 44, 45 and a second adsorption member moving mechanism 46 for causing the second adsorption members 44, 45 to reciprocate between the two positions. In FIG. 2, the second suction members 44 and 45 are drawn with solid lines at the third receiving position and with virtual lines at the third delivery position. Since this bag supply device 8 is W-shaped, two sets of second suction members 44 and 45 are installed for each bag 4 in total.
The second suction members 44 and 45 (the second suction member 44 is located on the upper side in the third receiving position and the second suction member 45 is located on the lower side) are connected by a conduit 47 having a predetermined length, A conduit 48 of the second adsorbing member 44 is fixed to a mounting stay 49 described later, and further communicated with a switching valve and a vacuum source (not shown) through a vacuum pipe 51.

第2吸着部材移動機構46は、一端が前記ボックスフレーム30に水平に回転自在に軸支された支点軸52と、支点軸52に一端が固定された揺動アーム53と、基部49aが揺動アーム53の他端の軸部53aに回動自在に軸支されて水平に延びる前記取付ステー49と、取付ステー49の基部49aに固定された軸部54と、軸部54を摺動自在に支持するガイドブロック55と、ボックスフレーム30に設置された支持部材56に固定され、ガイドブロック55の軸部57を回転自在に支持する軸受部材58と、一端が前記支点軸52に固定され、他端が連結部材59を介して図示しない駆動源に連結され上下揺動する昇降レバー61からなる(図4参照)。昇降レバー61が上下揺動することにより、揺動アーム53が袋4の供給方向に沿った鉛直面内において揺動し、同様に取付ステー49が上下に揺動する(図2の両矢印参照)。また、取付ステー49は、上方から下方への揺動に伴い、図2の実線及び仮想線から分かるように、揺動アーム53の軸部53aを中心に袋4の供給方向に対し逆向き(図2において右回転)に略180°回転する。結局、取付ステー49は、揺動アーム53の揺動に伴う供給方向に対する順向きの略90°の回転と、揺動アーム53の軸部53aを中心にした前記逆向きの略180°の回転が合計され、供給方向に対し逆向きの略90°の回転を行う。   The second adsorption member moving mechanism 46 has a fulcrum shaft 52 whose one end is pivotally supported by the box frame 30 so as to be horizontally rotatable, a swing arm 53 whose one end is fixed to the fulcrum shaft 52, and a base 49a swings. The mounting stay 49 that is pivotally supported by the shaft 53a at the other end of the arm 53 and extends horizontally, the shaft 54 that is fixed to the base 49a of the mounting stay 49, and the shaft 54 are slidable. A guide block 55 to be supported, a support member 56 that is fixed to the support member 56 installed in the box frame 30, a bearing member 58 that rotatably supports the shaft portion 57 of the guide block 55, one end is fixed to the fulcrum shaft 52, and others The end includes a lift lever 61 that is connected to a drive source (not shown) via a connecting member 59 and swings up and down (see FIG. 4). As the elevating lever 61 swings up and down, the swing arm 53 swings in the vertical plane along the supply direction of the bag 4, and similarly the mounting stay 49 swings up and down (see the double arrow in FIG. 2). ). Further, as the mounting stay 49 swings from above to below, as shown by the solid line and the phantom line in FIG. 2, the mounting stay 49 is opposite to the supply direction of the bag 4 around the shaft 53 a of the swing arm 53 ( Rotate approximately 180 ° (rightward rotation in FIG. 2). Eventually, the mounting stay 49 rotates approximately 90 ° in the forward direction with respect to the supply direction accompanying the swing of the swing arm 53 and rotates approximately 180 ° in the reverse direction around the shaft 53a of the swing arm 53. Are rotated approximately 90 ° in the opposite direction to the supply direction.

第2吸着部材44,45は、前記第3受取り位置において上下に位置するように配置され、吸着面は略垂直後方側(袋4の供給方向の後方側)に向き、前記第2引渡し位置にきた挟持部材31に挟持されて略垂直姿勢をとる袋4の前面(袋4の供給方向前面)を幅方向中央部の上下2カ所(それぞれ袋4の中央より袋口寄りの位置と袋底寄りの位置)で吸着する(図5の吸着部位B1,B2参照)。続いて挟持部材31が開いて袋4が挟持部材31から解放された後、第2吸着部材44,45は、揺動アーム53が揺動して取付ステー49が下方前方側に揺動するのに伴い、前記第3引渡し位置に向けて下方前方側に揺動し、かつ揺動アーム53の軸部53aを中心に回動して、前記第3引渡し位置にきたとき、吸着面は下向きの略水平状態となり、袋4も略垂直姿勢から略水平姿勢に変更される。
前記第3引渡し位置において、袋4はスパウト付き袋製造装置1の袋支持部材3上に置かれ(図2の仮想先参照)、可動部材11が下降して受け部材12との間で袋4の上縁部4a近傍を挟持し、第2吸着部材44,45が大気開放されて袋4を解放し、続いて前記第3受取り位置に向けて上昇移動する。
なお、第2吸着部材44,45で袋4の上下2カ所を吸着することにより、前記のとおり吸着部材44,45が移送中に回転しても、袋4の姿勢を安定して保持させておくことができる。
The second suction members 44 and 45 are disposed so as to be positioned vertically at the third receiving position, and the suction surface faces substantially vertically rearward (backward in the supply direction of the bag 4), and is at the second delivery position. The front surface of the bag 4 (front surface in the direction of supply of the bag 4) that is sandwiched between the holding members 31 and takes a substantially vertical position is located at two upper and lower positions in the center in the width direction. (Refer to adsorption sites B1 and B2 in FIG. 5). Subsequently, after the pinching member 31 is opened and the bag 4 is released from the pinching member 31, the second suction members 44 and 45 have the swing arm 53 swing and the mounting stay 49 swings downward and forward. Accordingly, the suction surface is turned downward when it swings downward and forward toward the third delivery position and rotates around the shaft 53a of the swing arm 53 to reach the third delivery position. As a result, the bag 4 is changed from a substantially vertical posture to a substantially horizontal posture.
In the third delivery position, the bag 4 is placed on the bag support member 3 of the spouted bag manufacturing apparatus 1 (see the virtual destination in FIG. 2), and the movable member 11 is lowered to the bag 4 between the receiving member 12. The second adsorbing members 44 and 45 are released to the atmosphere to release the bag 4 and then move upward toward the third receiving position.
In addition, by adsorbing the upper and lower portions of the bag 4 with the second adsorbing members 44 and 45, the posture of the bag 4 can be stably held even when the adsorbing members 44 and 45 rotate during the transfer as described above. I can leave.

また、空袋供給装置8は、第2吸着部材44,45による吸着を確実に行わせるために、2つの吸着補助手段を備えている。
1つは前記第3受取り位置において上側に位置する第2吸着部材44に対する吸着補助手段であり、これは挟持部材31が第2引渡し位置にきたとき後方側となる挟持片34に形成された延長部34aである。第2吸着部材44が、挟持部材31に挟持され略垂直姿勢にある袋4の前面側を前記第3受取り位置において吸着するとき(図5の吸着部位B1参照)、この延長部34aが第2吸着部材44の吸着面に対向して袋4の後面側を支持する。これにより第2吸着部材44による袋4の吸着が確実に行われる。
Further, the empty bag supply device 8 includes two suction assisting means in order to surely perform the suction by the second suction members 44 and 45.
One is a suction assisting means for the second suction member 44 located on the upper side in the third receiving position, and this is an extension formed on the sandwiching piece 34 on the rear side when the sandwiching member 31 comes to the second delivery position. Part 34a. When the second adsorbing member 44 adsorbs the front side of the bag 4 held between the holding members 31 in a substantially vertical position at the third receiving position (see the adsorbing part B1 in FIG. 5), the extension 34a is the second one. The rear surface side of the bag 4 is supported facing the suction surface of the suction member 44. Thereby, the suction of the bag 4 by the second suction member 44 is reliably performed.

もう1つは前記第3受取り位置において下側に位置する第2吸着部材45に対するもので、挟持部材31の前記第2引渡し位置の下方位置に設置された吸着補助手段62である。吸着補助手段62は、略水平状態となる退避位置と略垂直状態となる吸着補助位置の間で往復移動するプレート状の吸着補助部材63と、吸着補助部材63に前記両位置の間で往復移動を行わせる吸着補助部材移動機構64を備える(図4参照)。なお、図2において、吸着補助部材63は、退避位置では仮想線で、吸着補助位置では実線で描かれ、その移動(揺動)経路が両矢印で描かれている。袋供給装置8はW型であるので、この吸着補助部材63も並列に2個設置されている。
吸着補助部材移動機構64は、図4に示すように、ボックスフレーム30に回転自在に軸支された支点軸65(2つの吸着補助部材63が固定される)と、一端が支点軸65に固定され、他端が連結部材66を介して図示しない駆動源に連結され上下揺動する昇降レバー67からなる。昇降レバー67が上下揺動することにより、支点軸65が回動し、吸着補助部材63が揺動して前記退避位置と吸着補助位置の間を移動する。
The other is for the second suction member 45 located on the lower side in the third receiving position, and is a suction assisting means 62 installed at a position below the second delivery position of the clamping member 31. The suction assisting means 62 includes a plate-shaped suction assisting member 63 that reciprocates between a substantially horizontal retracted position and a substantially vertical suction assisting position, and the suction assisting member 63 reciprocates between the two positions. A suction assisting member moving mechanism 64 is provided (see FIG. 4). In FIG. 2, the suction assisting member 63 is drawn with a virtual line at the retracted position and with a solid line at the suction assisting position, and its movement (swinging) path is drawn with a double arrow. Since the bag supply device 8 is W-shaped, two suction assisting members 63 are also installed in parallel.
As shown in FIG. 4, the suction assisting member moving mechanism 64 has a fulcrum shaft 65 (two suction assisting members 63 are fixed) rotatably supported on the box frame 30 and one end fixed to the fulcrum shaft 65. The other end is connected to a drive source (not shown) via a connecting member 66 and is composed of a lifting lever 67 that swings up and down. As the elevating lever 67 swings up and down, the fulcrum shaft 65 rotates and the suction assisting member 63 swings and moves between the retracted position and the suction assisting position.

吸着補助部材63は、前記退避位置において挟持部材31と挟持部材31が挟持した袋4との干渉を避け、挟持部材31がその上を通過して前記第2引渡し位置にきた後、前記吸着補助位置に移動する。前記吸着補助位置にきた吸着補助部材63は、第2吸着部材45が挟持部材31に挟持され略垂直姿勢にある袋4の前面側を吸着するとき(図5の吸着部位B2参照)、第2吸着部材45の吸着面に対向して袋4の後面側を支持する。これにより第2吸着部材45による袋4の吸着が確実に行われる。   The suction assisting member 63 avoids the interference between the sandwiching member 31 and the bag 4 sandwiched by the sandwiching member 31 at the retracted position, and after the sandwiching member 31 passes over and reaches the second delivery position, the suction assisting member 63 Move to position. When the second suction member 45 is sandwiched between the sandwiching members 31 and sucks the front side of the bag 4 in a substantially vertical posture (see the suction site B2 in FIG. 5), The rear surface side of the bag 4 is supported facing the suction surface of the suction member 45. Thereby, the adsorption | suction of the bag 4 by the 2nd adsorption | suction member 45 is performed reliably.

以上説明した空袋供給装置8では、コンベアマガジン7aから第1吸着部材26で最上位の袋4を取り出すとき、複数枚取りが生じたとしても、全部の袋を挟持部材31で挟持して移送するので、移送中に余分な袋も落下することはなく、例えばコンベアマガジン7a上に落下してコンベアマガジン式給袋装置7からの次回の袋4の取り出しに支障が出ることはない。
また、複数枚取りが生じた場合でも、その袋を挟持部材31で挟持し、略水平姿勢から略垂直姿勢に変換しながら移送する過程で、袋間に空気が流入して密着状態が解消するから、次に第2吸着部材44,45で袋の前面側を吸着し、挟持部材31の挟持から袋を開放すると、実際に第2吸着部材44,45により吸着された袋のみはそのまま保持されているが、吸着されていない袋(複数枚取りされた余分の空袋)はその場で落下する。従って、複数枚取りされた袋がそのままスパウト付き袋製造装置1に供給されること(複数枚取り供給)が防止でき、また袋の落下位置が一定しており、余分の袋がスパウト付き袋製造装置1のテーブル2や袋支持部材3上に落下することも防止できる。
In the empty bag supply device 8 described above, when the uppermost bag 4 is taken out from the conveyor magazine 7a by the first suction member 26, even if a plurality of sheets are picked up, the whole bag is held by the holding member 31 and transferred. Therefore, excess bags do not fall during the transfer, and for example, they do not fall on the conveyor magazine 7a and do not hinder the next removal of the bags 4 from the conveyor magazine type bag feeder 7.
Even when a plurality of sheets are picked up, the bag is clamped by the clamping member 31, and in the process of being transferred while being converted from a substantially horizontal posture to a substantially vertical posture, air flows between the bags and the tight contact state is eliminated. Then, when the front side of the bag is adsorbed by the second adsorbing members 44 and 45 and the bag is released from the nipping of the holding member 31, only the bag actually adsorbed by the second adsorbing members 44 and 45 is held as it is. However, bags that are not adsorbed (extra empty bags that have been removed) drop on the spot. Accordingly, it is possible to prevent a plurality of sheets from being supplied to the spouted bag manufacturing apparatus 1 as it is (multiple sheet supply), the bag dropping position is constant, and an excess bag is manufactured from the spouted bag. It can also prevent falling on the table 2 or the bag support member 3 of the apparatus 1.

上記空袋供給装置8は本発明の一例に過ぎず、本発明の範囲内で例えば次のような改変が可能である。
(1)上記の例では、第2吸着部材44,45は、第3受取り位置において、吸着面を略垂直後方側に向けた状態で略垂直姿勢の袋4を吸着し、第3引渡し位置に向かう過程で前記吸着面を供給方向に対し逆向きに略90°回転させ、第3引渡し位置では吸着面を下向きの略水平状態としたが、例えば取付ステー49を揺動アーム53に固定することで、前記吸着面に揺動アーム53の揺動に伴う順向きの略90°の回転のみ起こさせ、第3引渡し位置では吸着面を上向きの略水平状態として袋を袋支持部材上に置くこともできる。ただし、この場合、コンベアマガジン7a上と袋支持部材3上とで、袋4の袋口側と袋定側の向きの逆転は起こらない。また、袋支持部材と第2吸着部材との干渉を防止する必要がある。
The empty bag supply device 8 is merely an example of the present invention, and the following modifications are possible within the scope of the present invention.
(1) In the above example, the second suction members 44 and 45 suck the substantially vertical bag 4 in the third receiving position with the suction surface facing the substantially vertical rear side to the third delivery position. In the course of heading, the suction surface is rotated approximately 90 ° in the opposite direction to the supply direction, and the suction surface is set in a substantially horizontal state in the third delivery position. For example, the mounting stay 49 is fixed to the swing arm 53. Thus, only the forward rotation of approximately 90 ° associated with the swing of the swing arm 53 is caused to occur on the suction surface, and the bag is placed on the bag support member with the suction surface in the substantially horizontal state at the third delivery position. You can also. However, in this case, the reverse of the direction of the bag mouth side and the bag fixed side of the bag 4 does not occur between the conveyor magazine 7a and the bag support member 3. Further, it is necessary to prevent interference between the bag support member and the second adsorption member.

(2)上記の例では、第2吸着部材44,45が第3受取り位置から第3引渡し位置まで移動する間の袋4の姿勢を安定させるため、2個の第2吸着部材44,45を用いて袋4の上下2カ所を吸着したが、必要に応じて、1カ所だけ吸着するようにしても、3カ所以上吸着するようにしてもよい。
(3)上記の例では、第2吸着部材44,45が第3受取り位置から第3引渡し位置まで移動する間に、袋4を略垂直姿勢から略水平姿勢に変更したが、これは袋の供給先であるスパウト付き袋製造装置1に袋4を水平姿勢で供給するためである。しかし、例えば通常のロータリー式袋詰め包装機のグリッパー対に供給するときのように、袋を略垂直姿勢にして供給する場合もある。この場合、第2吸着部材は、袋4の略垂直姿勢を保ったまま、第3受取り位置から第3引渡し位置まで例えば単に水平移動すればよい。
(2) In the above example, in order to stabilize the posture of the bag 4 while the second suction members 44 and 45 move from the third receiving position to the third delivery position, the two second suction members 44 and 45 are used. Although the two upper and lower portions of the bag 4 are adsorbed by use, only one location may be adsorbed or three or more locations may be adsorbed as necessary.
(3) In the above example, the bag 4 is changed from the substantially vertical posture to the substantially horizontal posture while the second suction members 44 and 45 move from the third receiving position to the third delivery position. This is because the bag 4 is supplied in a horizontal posture to the spouted bag manufacturing apparatus 1 which is a supply destination. However, there is a case where the bag is supplied in a substantially vertical posture, for example, as in a case where the bag is supplied to a pair of grippers of a normal rotary type bag filling and packaging machine. In this case, the second suction member may simply move horizontally, for example, from the third receiving position to the third delivery position while maintaining the substantially vertical posture of the bag 4.
